CI/CD describes the automated pipeline that takes a code change from a developer's commit through testing, building, and deploying — without manual intervention. 'CI' is the test-and-build half; 'CD' is the deploy half.
What it is
CI/CD describes the automated pipeline that takes a code change from a developer's commit through testing, building, and deploying — without manual intervention. 'CI' is the test-and-build half; 'CD' is the deploy half.
How it actually works
Continuous Integration (CI) means every code commit triggers an automated build and test run. The goal is to catch breaks within minutes of when they're introduced, while the code is still fresh in the author's mind. Without CI, breaks are discovered hours or days later, after multiple developers have built on top of them, making them painful to untangle.
Continuous Deployment (CD) means every passing build goes to production automatically. Continuous Delivery is the slightly more conservative variant where every build is deployable, but a human triggers the actual deploy. Mature teams use Continuous Deployment for most code paths and Continuous Delivery for high-risk areas like database migrations.
A standard 2026 pipeline: commit → run tests in parallel → build container image → push to registry → run integration tests against ephemeral environment → if passing, deploy to staging → automated smoke tests → if passing, deploy to production via blue-green or canary rollout. End-to-end time: typically 10-30 minutes.
Why teams skip CI/CD initially: setup takes 1-2 weeks; the payoff is in shorter feedback loops and faster recovery from breaks, which compound over months. Teams without CI/CD eventually rebuild it under another name once shipping speed becomes a bottleneck.
